Answer: 198m²
Step-by-step explanation: PT = 11 ; PR = 22
PRxQT = area
22XQT = 22x9 = 198
Lines that are pendicular has slopes that multiply to -1
if m1=-5/2, then m2 times m1=-1
-5/2 times ?=-1
times both sides by -2/5
?=2/5
m2=2/5
the slope of line 2 is 2/5
A. the first one will give you a perpendicular line to BA
We need to write a proportion to solve this
7/3=35/x
105=7x
divide each side by 7
15=x so, there were 15 burgers without cheese.
We could add the cheese burgers 35 to burgers without cheese 15
35+15=50 burgers were sold.
I love math. Well the formula is y=mx+b. the slope is m so the answer is 7
